See [transfer timestamps](/transfer-outcome-states#transfer-timestamps). ## New transfer outcome states A transfer that reaches a phone menu, a voicemail greeting, or a busy line now reports that instead of a generic timeout. If you match on outcome state, add the values from the full list of [transfer outcome states](/call-transfers#transfer-outcome-states). ## Action execution timeline in webhooks A transfer that retried three times used to show up as one attempt in the post-call webhook. The new [action execution timeline](/webhooks#action-execution-timeline) lists every attempt and the number each one dialed.
